4-Brom-benzolsulfonsaeure-<2-cyclopentyl-ethylester>, also known as 4-bromobenzene sulfonic acid 2-cyclopentylethyl ester, is a chemical compound with the molecular formula C13H17BrO3S. It is an ester derivative of 4-bromobenzene sulfonic acid, featuring a cyclopentylethyl group attached to the ester moiety. 4-Brom-benzolsulfonsaeure-<2-cyclopentyl-ethylester> is characterized by its bromine atom attached to the benzene ring, which may contribute to its reactivity and properties. It is likely used in organic synthesis, potentially as an intermediate in the production of pharmaceuticals, agrochemicals, or other specialty chemicals. Due to the presence of a bromine atom and a sulfonic acid group, it may exhibit unique chemical reactivity, such as electrophilic substitution or nucleophilic attack at the benzene ring. The cyclopentylethyl ester group provides additional structural complexity and may influence the compound's solubility, stability, and biological activity.
The CAS Registry Mumber 6749-58-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6749-58: (6*6)+(5*7)+(4*4)+(3*9)+(2*5)+(1*8)=132 132 % 10 = 2 So 6749-58-2 is a valid CAS Registry Number.
